Geoinformatics: Collaborative Research: Proposal to enhance the experimental petrology database LEPR and to develop interoperability between LEPR and EarthChem

0744039 Walker该奖项提供资金，以改善实验阶段关系库(LEPR)，并开发LEPR与地球化学数据库的互操作性机制。LEPR是来自近7,000个岩浆相平衡实验的成分和辅助数据的关系型数据库。EarthChem数据库包含了超过23万块自然形成的火成岩的成分、地理分布和其他数据。该项目的目标是：1)简化LEPR的数据录入过程，并使其部分自动化，以便于更新，并使实验者社区中的潜在贡献者能够将其已公布和未公布的数据存档；2)提高查询能力，纳入用于分析数据子集的建模工具，并开发在LEPR中操纵数据的实际例子，以促进将数据库用于研究和教学目的；3)开发一个程序，允许用户交叉关联LEPR和地球化学火成岩数据库之间的数据。对LEPR的改进和LEPR-EarthChem互操作性的建立将使更广泛的科学家社区能够将这些数据库用于研究和教学。学生将可以访问项目的真实数据，而不必费力从多个不同的来源收集数据。最重要的是，增强的LEPR和LEPR-EarthChem连接将创建一个数据挖掘环境，促进从不同数据源进行综合和模型开发。

0744039WalkerThis award provides funding to improve the Library of Experimental Phase Relations (LEPR) and to develop a mechanism for interoperability of LEPR with the EarthChem database. LEPR is a relational database of compositional and ancillary data from almost 7,000 magmatic phase equilibrium experiments. The EarthChem data base contains composition, geographic distribution and other data on over 230,000 naturally occurring igneous rocks. The goals of the project are: 1) to streamline and partially automate the process of data entry to LEPR in order to facilitate updates and to enable potential contributors in the community of experimentalists to archive their published and unpublished data, 2) to improve query capabilities, incorporate modeling tools for analysis of data subsets, and develop practical examples of manipulating data in LEPR in order to motivate use of the database for research and for pedagogical purposes, and 3) to develop a process that will allow users to cross correlate data between LEPR and the EarthChem igneous rock databse.The enhancements to LEPR and the establishment of LEPR-EarthChem interoperability will enable a wider community of scientists to make use of these databases for research and for teaching. Students will have access to real-world data for projects without the hassle of having to gather data from a number of disparate sources. Most importantly, an enhanced LEPR and the LEPR-EarthChem connection will create a data-mining environment that promotes synthesis and model development from diverse data sources.
